July 14, 1931. A. D. M CORMACK AUTO WINDOW SCREEN Filed Dec. 4. 1929 Patented July 14, 1931 UNITED STA ALFRED MQCORMAGK, OF M ANKATO, MINNESOTA AUTO WINDOW sonnmv Application filed December 4, 1929.

'My invention relates to screen sash of the class particularly adaptable for use in motor vehicles but also applicable to railway coach windows or windows of any structure havmg vertically ad ustable window glass.

Fig. 1 is a side elevation of an automobile of the so-called coach type in the front window of which my improved screen is shown fully covering the opening and its rear window having one of my screens only raised part way in the opening.

Fig. 2 is a face view of my improved screen in enlarged scale and Fig. 3 is a right hand end elevation of Fig.2. i

' Fig. 1- is' a fragmentary view of an end portion of, my improved screen and a certain Xtension bar therefor.

Fig. 5 is an end elevation of the upper part of Fig. 4: showing the extension bar fixed to the screen end bar.

Fig, 6 is an enlarged sectional detail of the right hand part of the rear screen in .Fig. 1 and adjacent parts, about as on line 6.6 in said Fig. 1.

Fig. '1 is an enlarged vertical cross section of a screen and parts of a carbody about as on line '('.7 in Fi 1.

Figure 8 is an enlarged cross sectional detail view of the lower bar 11, modified.

Referring to the drawings by reference numerals, my improved screen in a preferred form is quadrangular and comprises parallel upper and lower sash bars 10 and 11 respectively, each bar comprising two connected elongated fiat metal pieces, and like vertical side bars 12 and 13 right and left respectively, a screen 14 being retained between the two thicknesses of all said bars in suitable taut condition. Said horizontal Serial No. 411,529.

18, and 19 is the window opening of the door. In each said window openings is a vertically movable pane 20, the opposite vertical edges of which are guided within suitable padding strips 21 usually of U shape in cross section and retained within the grooved upright channel parts 22of the window casing 23.

Inmotor cars the windows 20 are raised or lowered by various means '(not shown') to move the glass to any desired position.

My improved screen is adapted to be inserted in a window opening of the class described, outwardly of the pane: 20 and in parallel plane therewith. In general its shape is quadrangular as stated but for windows having an arched topthe upper bar 10 may be formed to correspond with said curvature.

rear memberof the vertical bars extends below the lower horizontal bar 11 and provide downwardly and outwardly curved, prefer ably tapered guide pieces 12G and 13G.-

'24 area number of, preferably two, finger grips of L-shape and fixed on the outer face of the bar 10. In Figs 2 and Bis shown also that the rear side-bar members 1213 are each formed at is upper end with a forwardly directed short hook or finger 12F 13F, these for the purpose of engaging a ledge 25 usually extending across' and formed integral of the lintel of the window frame, particularly in motor cars, thus sus pending the screen .while in raised position and covering the window opening. The screen is of such size that'when suspended as just described its lower bar llis prefer ablyslightlybelow the window sill as indicatedby the dotted line 11X inFig. 1.

The screen is insertedreadily by holding it in vertical plane and bowing it horizontally to shorten the distance between the side bars until the guide pieces 10G can be en gaged between the padding strip 21 in front of the glass and the adjacent face of groove 22, the lower part of, the screen being in serted first at the lowerpart of the window opening and pushed down until the bowed upper part of the screen can be released and the guides 10G slide into place. To prevent any tendency of the screen to rattle, its side bars are provided with a number of bowed fiat springs 26, causing the screen to bear outwardly at all times when in place.

In Fig. 4, 12F are auxiliary fingers on bar 10 corresponding to the fingers 12F described. These may not be needed except for screens of considerable width.

The lower guides 12G of the side bars guide the said parts of the screen vertically when the screen is raised or loweredand being curved forwardly engage the outer face of the frame groove in which the sash 20 slides and pushes the screen back so it will not catch on the sash frame.

After getting the screen in place the operator simply exerts upward pressure on the finger holds 2 1 and until the hooks 12F engage ledge 25. 'Obviously the screen will remain in place. To release the screen the operator merely engages the finger-pieces 24, bears inwardly until the hooks 12F are released and the screen may be lowered until the said finger-pieces contact with the win dow sill 27 (see dotted position of 24 in Fig. 7) and at this time the screen is entirely out of the window opening.

An important feature of my invention is shown in Figs. 4 and 5 comprising an auxiliary side bar 28. At the upper end of'this bar 28G is an outward extension corresponding to extension 10G of bar '10 in Fig. 2, the screen bar 10 in this instance having no extension lOG; and further the upper extremity is provided with a forwardly directed finger 12F serving the same purpose as finger 12F, and a lower projection 28G corresponding to 12G of bar 12 in Fig. 2.

. Springs 26 are provided on this bar. The bar 28 is fixed to bar 12 by riveting them together at the groups of holes designated 29 on both bars, the bar 28 being of considerable width and the groups of holes 29 so arranged thatbar 28, can be fixed to bar 12 so as to hold the former outwardly from the bar 12. This actually provides a combination side bar which is variable or in other made and the variable widths compensated for by simply fixing bar 28 to bar 12 as needed to properly cover the window openm To insure that the lower bar 11 is rigid enough to remain in proper s aced relation to the pane said bar may e flanged or curved outwardly as its lower edge as 11F in Fig. 9 for stiffening it. Other modifications may also be embodied without departing from the scope and spirit of the invention.

I claim: L

1. In a screen of the class described for structures having window openings and a pane movable between vertical frame guides thereof, a quadrangular screen holding metal frame, each side of said frame comprising a bar of two fiat members with an edge of the screen retained between them, one member of each side bar extending'below the bottom bar and curved forwardly, an anti-rattling means provided on, the rear face of each said side bar, guide extensions of said frame projecting outwardly from the upper corners, a number of forwardly directed integral fingers extending from the upper edge part of the upper frame bar and finger holds fixed on said upper frame bar.
